What is the treatment?
Endodontic retreatment, or re-endodontics, is based on two main phases: the elimination of the contents of the ducts and the remodeling, cleaning, disinfection and the final filling of the ducts.
Endodontic retreatment begins when there is a review of the patient’s medical history, a good clinical analysis along with the necessary complementary tests, a diagnosis of certainty has been obtained.
How is it performed?
The reendodontia begins with the placement of local anesthesia in the area and the subsequent absolute isolation, with the rubber dam, to prevent contamination throughout the treatment. Next, the restoration of the tooth is removed, including the crown or dental post that may exist in the tooth to be re-labeled. Then, the old duct filling material is removed and removed by means of files, solvents and intra-duct irrigators. When the ducts are completely free, disinfected and reconformed, the ducts are sealed.
